Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Rose-petalled Jellyskin Lichen faces severe threats from air pollution, particularly nitrogen deposition and sulfur compounds, which dramatically alter the chemical composition of its substrate and surrounding environment. Habitat loss through urbanization and agricultural intensification has eliminated many suitable sites, while climate change is altering moisture regimes essential for this gelatinous lichen's survival and reproduction.
Key Facts
Habitat & Distribution
This gelatinous lichen grows on the bark of deciduous trees, particularly in humid woodlands, parklands, and along hedgerows where moisture levels remain consistently high. It favors nutrient-rich bark of mature trees in areas with clean air and stable microclimatic conditions.
